Might try burying a length of hardware cloth (mesh screening stuff)

ground to try it out. If the dog persists or goes around it, I would
seriously consider trading him in.

Animals that damage the home

Goldfish are pets. Dogs and cats are members of the family.

You wouldn't "trade-in" a toddler who left teeth-marks on the coffee table.

Damage to property is something you have to accept from a member of the
family.
